Title: Method for transferring paper in printer
Inventor: HAYASHI TORU
IPC: B65H9/14
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To highly accurately transfer papers by a platen drum in a constitution whereby the papers are transferred by a different driving roller from the platen drum. SOLUTION: A platen drum 2 transfers a long paper 30 in a predetermined direction while winding the paper 30 on a surface thereof and intermittently rotating. A pinch roller 14 holds the paper 30 and transfers the paper in a predetermined direction. A driving roller 20 of the pinch roller 14 is synchronously started to rotate with the start of the intermittent rotation of the platen drum 2. A peripheral velocity of the driving roller 20 is instantaneously made higher than a peripheral velocity of the platen drum 2 when the driving roller 20 is started to rotate, thereby impressing a tension to the paper 30 between the pinch roller 14 and platen drum 2. Then, the peripheral velocity of the driving roller 20 is synchronized with that of the platen drum 2, and subsequently, the driving roller 20 is stopped a predetermined time before the platen drum 2 stops.  A slack 30a is thus provided to the paper 30.
